The airline business is a strange business and in desperate need for business model innovation. On the one hand, more people fly than ever to prices lower than ever. IATA, the industry body, states that the real cost of travel has fallen in the last 40 years by about 60% and the number of travelers increased tenfold. Air freight has grown in this period by a factor of fourteen. (See IATA Vision 2050) That sounds like a very successful industry. Is it? However, on the other hand, airlines are notorious to not even earning their cost of capital and producing unhappy customers.
